    The Best Bang-For-Your-Buck TV Enhancement? Scenic Labs LX1 Bias Lighting Kit, a Full Review

    Bias lighting would demand a neutral wall, ideally white (255, 255, 255). Since none of us have a perfect white wall, we do the best we can. I could see neutral grays working but you'll need to up the power on the lights, which could produce spotlighting. I've reduced that by using a COB type...

    Dual Rythmik FV18’s

    Looks great. Those cars are definitely going to be rolling off the sub in short order.

    Dual Rythmik FV18’s

    They work down to about 80-100 Hz.

    Dashboard

    Building on the excellent measurement process already in place, perhaps REW could package the results into a dashboard view for easy reference. It could display frequency response with an adjustable +/- dB highlight, strength of early reflections, early vs late sound ratio, RT60, spectrograph...

    The Best Bang-For-Your-Buck TV Enhancement? Scenic Labs LX1 Bias Lighting Kit, a Full Review

    There are a lot of LED products claiming "CRI 95" now, until you read the fine print after buying. It's nice to see them actually providing measurements that prove it.

    NAD T 758 v3 A/V Surround Sound Receiver Review

    When I had my T758, the fans ran 100% of the time if I used the RCA preouts, and they were audible.

    DSP: EQ’ing Full Range or Not – Testing the Ears

    I can do some impulse measurements. How much resolution is needed to look for this effect? What frequency are we defining how long one "cycle" is? And are we looking at the start of the impulse, or the peak? Remember sound starts before the peak. 100 Hz = 10 ms 90 Hz = 11 ms 80 Hz = 12.5 ms 70...

    DSP: EQ’ing Full Range or Not – Testing the Ears

    It is not psychoacoustics. It is the result of measuring a room with an omnidirectional microphone as directivity of tweeters narrows and loads the room less and less.

    DSP: EQ’ing Full Range or Not – Testing the Ears

    I have a feeling you don't own modern HT equipment, is that right? When we set up subs and speakers, we don't take into account the video at all. We are only aligning the sound from all speakers and subs to our seats. When a delay is needed for the video, which is typically only with...

    DSP: EQ’ing Full Range or Not – Testing the Ears

    In 10+ years I have never heard this. Do you have a link?

    DSP: EQ’ing Full Range or Not – Testing the Ears

    I am not, either. I'm talking aligning subs to each other.

    So yours are tuned and not broadband? That changes things.

    But they are interrelated. Adjusting delays affects the frequency response.

    DSP: EQ’ing Full Range or Not – Testing the Ears

    Achieving a smooth frequency response is the result of managing delays and equalization and is talked about all the time with regard to subwoofers. This is bass decay. Step one is delays and equalization to smooth the response which greatly enhances bass decay. What's left below 100 Hz (from...

    DSP: EQ’ing Full Range or Not – Testing the Ears

    It actually sounds balanced to my ears. The key is that your sub bass slopes down into the upper bass by ~120-150 Hz at most. The standard Harman curve continues to boost higher than that and in my experience does not sound as clean. Not sure what you mean by time domain behavior. Of course we...
